No you're not creating confusion @Incongruous, those bars are all basically test bars, testing for supply (testing that any supply is not overwhelming), and in the process potentially allowing the market operator to hit SLs (allowing them to further accumulate cheaper supply). In an uptrend they are a sign of strength, and they also offer (us) a point at which to enter.

If you weren't sure before that it was accumulation, when you see that behaviour you can be pretty positive that it was.

Big thumbs up for providing a near text book example
